LM4040/4041

Precision Micropower Shunt Voltage Reference

General Description

Features

Ideal for space critical applications, the LM4040 and LM4041

precisionvoltagereferencesareavailableinthesubminiature

(3mm × 1.3mm) SOT-23 surface-mount package.

• Small SOT-23 package

• No output capacitor required

• Tolerates capacitive loads

• Fixed reverse breakdown voltages of 1.225, 2.500V,

4.096V and 5.000V

• Adjustable reverse breakdown version

• Contact Micrel for parts with extended temperature

range.

The LM4040 is the available in ﬁxed reverse breakdown

voltages of 2.500V, 4.096V and 5.000V. The LM4041 is avail-

able with a ﬁxed 1.225V or an adjustable reverse breakdown

voltage.

The minimum operating current ranges from 60µA for the

LM4041-1.2 to 74µA for the LM4040-5.0. LM4040 versions

have a maximum operating current of 15mA. LM4041 ver-

sions have a maximum operating current of 12mA.

Key Speciﬁcations

• Output voltage tolerance .............................±0.1% (max)

• Low output noise (10Hz to 100Hz)

The LM4040 and LM4041 have bandgap reference tempera-

ture drift curvature correction and low dynamic impedance,

ensuring stable reverse breakdown voltage accuracy over a

wide range of operating temperatures and currents.

LM4040................................................. 35µV

LM4041................................................. 20µV

• Wide operating current range

LM4040..................................................60µA to 15mA

LM4041..................................................60µA to 12mA

• Industrial temperature range .................. –40°C to +85°C

• Low temperature coefﬁcient ................ 100ppm/°C (max)
